8. Starting from the Internet
• Internet appears everywhere in the world
• but it is still a connection between people and people

9. What is the Internet of Things?
• Internet connects all people, so it is called “the Internet of People”
• IoT connects all things, so it is called “the Internet of Things”

10. What’s the Internet of Things
 Definition
(1) The Internet of Things, also called The Internet of
Objects, refers to a wireless network between objects,
usually the network will be wireless and self-configuring,
such as household appliances.
------Wikipedia
(2) By embedding short-range mobile transceivers into a
wide array of additional gadgets and everyday items,
enabling new forms of communication between people
and things, and between things themselves.
------WSIS 2005

11. What’s the Internet of Things
 Definition
(3) The term "Internet of Things" has come to describe a
number of technologies and research disciplines that
enable the Internet to reach out into the real world of
physical objects.
------IoT 2008
(4) “Things having identities and virtual personalities
operating in smart spaces using intelligent interfaces to
connect and communicate within social, environmental,
and user contexts”.
-------IoT in 2020

12. What’s the Internet of Things
• History
 1997, “The Internet of Things” is the seventh in the series of ITU
Internet Reports originally launched in 1997 under the title
“Challenges to the Network”.
 1999, Auto-ID Center founded in MIT
 2003, EPC Global founded in MIT
 2005, Four important technologies of the internet of things was

20. The Application of IoT(1)
Network
Biosensor taken by people
Equipment in
public place
House
Regional Office
Virtual Environment
Transportation Vehicle

21. The Application of IoT(2)
Scenario: shopping
(2) When shopping in the market, the
goods will introduce themselves.
(1) When entering the doors, scanners
will identify the tags on her clothing.
(4) When paying for the goods, the
microchip of the credit card will
communicate with checkout reader.
(3) When moving the goods, the reader
will tell the staff to put a new one.

22. The Application of IoT(3)
Scenario: Health Care
• Various sensors for various
conditions
• Example ICP sensor: Short or
long term monitoring of
pressure in the brain cavity
• Implanted in the brain cavity
and senses the increase of
pressure
• Sensor and associated
electronics encapsulated in
safe and biodegradable
material
• External RF reader powers
the unit and receives the
signal
• Stability over 30 days so far

23. • National Health Information Network,
Electronic Patient Record
• Home care: monitoring and control
Pulse oximeters, blood glucose monitors, infusion
pumps, accelerometers, …
• Operating Room of the Future
Closed loop monitoring and control; multiple treatment
stations, plug and play devices; robotic microsurgery
System coordination challenge
• Progress in bioinformatics: gene, protein
expression, systems biology, disease
dynamics, control mechanisms
The Application of IoT(3)
Scenario: Health Care

24. The Application of IoT(4)
Scenario: Intelligent Home
• Remote monitor for
smart house
• Remote control for
smart appliance

25. The Application of IoT(5)
Scenario: Transportation
• A network of sensors set up throughout a vehicle can interact with its
surroundings to provide valuable feedback on local roads, weather and
traffic conditions to the car driver, enabling adaptive drive systems to
respond accordingly
• This may involve automatic activation of braking systems or speed control
via fuel management systems. Condition and event detection sensors can
activate systems to maintain driver and passenger comfort and safety
through the use of airbags and seatbelt pre-tensioning
• Sensors for fatigue and mood monitoring based on driving conditions,
driver behaviour and facial indicators can interact
to ensure safe driving by activating warning systems
or directly controlling the vehicle

26. • In 2005, 30 – 90 processors per car
Engine control, Break system, Airbag deployment system
Windshield wiper, Door locks, Entertainment system
• Cars are sensors and actuators in V2V networks
Active networked safety alerts
Autonomous navigation
• Future Transportation Systems
Incorporate both single person and mass transportation vehicles, air and ground
transportations.
Achieve efficiency, safety, stability using real-time control and optimization.

the data of
things
To collect
and process
the data to
detect the
changes in
the physical
status of
things
To enhance the
power of the
network by
devolving
processing
capabilities to

the network.
To make the
smaller and
smaller things
have the
ability to
connect and
interact.
Enabling Technologies

29. Sensor Technology
The ability to detect changes in the physical status of things is
essential for recording changes in the environment.
Wireless sensor technology play a pivotal role in bridging the
gap between the physical and virtual worlds, and enabling
things to respond to changes in their physical environment.
Sensors collect data from their environment, generating
information and raising awareness about context.
Example: sensors in an electronic jacket can collect information about
changes in external temperature and the parameters of the jacket can be
adjusted accordingly

× WSN is IoT， IoT aka WSN  IoT ＝ WSN
× IoT aka RFID + PerCom
√ IoT is not WSN IoT ≠WSN
IoT contains WSN IoT ≥WSN

35. IoT and WSN
• Things are diverse
• They might be individual like water, soldiers,
trees…
• They also be a set of individuals like ocean,
battlefield, forest, …

36. IoT and WSN
We concern not only about water, tree and soldier, but also
about ocean, forest and battlefield.

37. IoT and WSN
